Under the terms of a deal with the Manhattan District Attorney’s Office, Watt, 75, pleaded guilty to criminally negligent homicide for killing Grove with his experimental “carbon dioxide therapy.” Watt gets no jail time or probation, but did have to surrender his medical license.

“Our daughter went to see what she thought was a doctor. What she went to see was a stinkin’ quack . . . a charlatan,” he vented.

Leah, a sales executive, had gone to see Watt for treatment of mild depression.

Grove noted that when Leah, 39, went into cardiac arrest in Watt’s office, the doctor didn’t try to resuscitate her or call 911 – he left that to a friend of hers who was in the office.

Grove urged the doctor to “do society a favor” and take his own life.

A concerned Solomon then asked prosecutor Gail Heatherly to explain the no-jail deal. She said her office had investigated the case thoroughly, but her hands were tied because of laws that make it difficult to prosecute doctors, and the deal was the best they could do.

Solomon then signed off on the sentence, but said his heart was with Grove.
